Three-Pack Li-Ion Replacement Batteries

This Kastar three-pack supplies 1400 mAh 3.7 V lithium-ion cells rated at 5.18 Wh each. They are built as direct replacements for the SeaLife FJ-SLB-SLB10A pack used in the DC2000 underwater camera.

Practical Limits of the Standard

Each cell delivers a fixed 3.7 V nominal voltage and 1400 mAh capacity, so runtime scales linearly with the number of packs carried. The chemistry cannot exceed its rated watt-hours, and the built-in protection circuit will cut output if current, voltage or temperature move outside safe bounds.

Upgrade Path and When It Matters

The pack replaces the original SeaLife battery and also fits Zoom BT-02 and 247-9036 models used in Q4 and Q4n recorders. Buyers who need more storage than three packs provide will have to carry additional sets or choose a different power solution.

Questions about this item

Should I buy the 3-pack or look for a single SLB-10A battery?

The 3-pack delivers three 1400mAh cells so you can keep shooting while two charge, ideal for long dive trips with the DC2000.

What does the 1400mAh rating actually give me in the SeaLife DC2000?

At 3.7V and 5.18Wh each cell powers the DC2000 for extended video sessions, matching the original FJ-SLB-SLB10A runtime.

Does the battery use a proprietary connector or a standard USB interface?

The SLB-10A fits the DC2000 battery bay directly and charges in the SeaLife charger or compatible Zoom LBC-1 unit, no USB port on the cell.
